If I understand you correctly, you are asking why are you not getting
"2010-02-24 17:08:22.138 DEBUG 3055020960  main loggerbase.cpp:3944" header
for every line? If that is the question then the answer is because the header
is only being printed for each instance of InternalLoggingEvent object that
is created internally by the LOG4CPLUS_DEBUG() macro. It is not printed for
each textual line of output.

Your filelogger is using the same appender as rootLogger. Are you not getting
duplicate log entries if you log anything using the filelogger?
